Part of the Top Notch series, this right-hand insert carries a TiAlN finish applied via PVD coating, which improves wear resistance and tool life in demanding threading operations. The insert is manufactured to a KC5010 grade with a C3\/C4 material classification. It measures 0.1949 inches thick with a tip-to-top height of 0.1071 inches and a corner radius of 0.0161 inches. These close tolerances make it suitable for consistent thread form on production runs. Machinists and CNC operators working with lathes and turning centers in metalworking shops are the primary users.\u003c\/p\u003e\u003cp\u003eThis insert is used for external threading of UN-standard fastener threads at 8 TPI, a common pitch for larger-diameter bolts and fittings in industrial and mechanical assembly. The 60-degree included angle conforms to the standard UN\/UNC\/UNF thread form. The Top Notch series mounting system provides rigid insert clamping in compatible Top Notch toolholders. It is well-suited for production threading in steel and alloy materials where TiAlN coating delivers thermal and abrasion resistance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide substrate with TiAlN finish via PVD coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e8 TPI external threading for UN-standard thread form\u003c\/li\u003e\n\u003cli\u003e60-degree included angle matches UN\/UNC\/UNF thread geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut configuration for standard lathe threading operations\u003c\/li\u003e\n\u003cli\u003eTop Notch series insert style for rigid, repeatable clamping in compatible holders\u003c\/li\u003e\n\u003cli\u003eInsert size 3 with tight dimensional tolerances for consistent thread accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENNAMETAL Top Notch series threading toolholders that accept NTC3 style inserts.

Power down and lock out the machine before seating or replacing the insert. Use the appropriate Top Notch clamp and torque the clamping screw per the toolholder manufacturer specifications. Inspect the insert seat and clamp for wear or debris before installation to ensure proper seating and thread form accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTC3R8E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Pitch\u003c\/strong\u003e: 8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.1071 inches (2.72 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0161 inches (0.41 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1949 inches (4.95 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1764 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1765641\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738744226098,"sku":"1765641","price":243.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8892e28449d441813a90f1fa66984785.jpg?v=1788803737","url":"https:\/\/voomisupply.com\/products\/kennametal-1765641-threading-insert-8-tpi-kc5010-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
